Myelination, the process by which glial cells ensheath the axons of neurons in layers of myelin, ensures the rapid conduction of electrical impulses in the nervous system. The formation of myelin sheaths is one of the most spectacular examples of cell-cell interaction and coordination in nature.
Most axons are surrounded by an insulating layer of lipid combined with protein called myelin. The myelin sheath functions to electrically insulate the axon. This greatly increases the speed of conduction of nerve impulses. The amount of myelination increases from birth through adulthood.
